Step-by-Step Guide to Fixing the Check Charging System Warning
Follow these steps to troubleshoot and fix the 'Check Charging System' warning in your Acura:
Step 1: Gather Required Tools
Before starting, ensure you have the following tools:
- Multimeter

Step 2: Inspect the Battery
Check for any corrosion on the battery terminals. Clean the terminals if necessary. Use a multimeter to check the battery voltage:
- Normal voltage: 12.6V or higher (engine off)
- Charging voltage: 13.7V to 14.7V (engine running)
Step 3: Test the Alternator
With the engine running, measure the voltage at the battery terminals again. If it’s below 13.7V, the alternator may be faulty. Check the wiring and connections for any damage.
